In this lull between fun summer TV like “True Blood” and the fall premieres of network television shows, many people have been binge watching the Netflix comedy, “Orange is the New Black.” Set at a women’s prison in Rockland County, New York, the series has generated new interest in jail. (From the outside, at least.) Here are five notable prison museums around the world with flexible visiting hours for an easy escape.

Alcatraz, San Francisco, CA
Built as an “inescapable” prison on an island off San Francisco, Alcatraz has had quite a few famous inmates, including Al Capone. The federal prison was closed in 1963 and has been a museum for several decades. In addition to the prison museum, it also has the country’s oldest lighthouse and a permanent exhibition on the historic Native American occupation. Tickets are a steep $30 and up per adult, but they include transportation, since you can’t make it off “the Rock” alive.Eastern State Penitentiary, Philadelphia, PA
Another stop on Al Capone’s “jail tour,” this Center City Philadelphia jail has been the set for several films including “Twelve Monkeys” and the Transformers sequel, and many TV shows about ghosts and jails. The self-guided audio tour (narrated by Steve Buscemi!) details the history of the prison, active from 1829 to 1969. Regular tickets are $14, and look out for special events; the Halloween Haunted House is especially popular.

Robben Island, Cape Town, South Africa
The isolation of the small island near Cape Town made it a fitting site for a leper colony, a military training station and a place for political prisoners. Nelson Mandela was the most famous of former inmates for 18 years; he was one of dozens imprisoned during apartheid. Tickets are about $22, including ferry transportation to and from the mainland, a bus tour of the island and “interaction” with a former prisoner. President Obama visited the island and museum this summer, and was “deeply humbled” by the experience.

Tuel Sleng, Phnom Penh, Cambodia
The secret prison of Pol Pot, dictator of Cambodia in the 1970s and leader of the Khmer Rouge, Tuel Sleng is now a museum cataloging the genocide perpetrated there. The museum contains the 6,000 detailed photographs and records of inmates left by prison staff, though as many as 30,000 were said to have been detained, tortured and murdered there. The museum is preserved as it was found in 1979, and is an important site, along with the “Killing Fields,” documenting and memorializing the victims of this dark regime.

What’s a feast day? Certain Christian traditions, notably Roman Catholic, keep track of which liturgies are given when by way of something called the General Roman Calendar, or Universal Calendar of Saints. Around 60 percent of the days of the Gregorian calendar year are associated with one or more saints, martyrs or holy figures. Even some relics have feast days. The feast day for St. Peter’s chair is on February 22. St. John the Baptist’s feast day falls on June 24.

Interestingly, St. Christopher, the patron saint of travelers, lost his feast day back in 1969. A lot of people think St. Christopher was “desanctified,” or lost his sainthood, but in fact he was just stripped of his feast day because there’s no proof he actually existed.

Also interestingly, the patron saint of travelers is also the patron saint of bachelors and bookbinders, among other things.

You were saying about St. John the Baptist… Right.

So why June 24 of all days? That’s when John the Baptist is said to have been born. But more than that, Christianity has a long tradition of co-opting pagan rituals into Christian holidays. It’s a good way to gain converts. Pagan celebrations generally aligned with the turning of the seasons – equinoxes and solstices. And so Christians have major holidays around these dates: Easter near the vernal equinox, Christmas near the winter solstice and Michaelmas, which celebrates Lucifer being cast out from heaven, near the autumnal equinox.That June 24 is close to the summer solstice is certainly not a coincidence. Even if the summer solstice used to be celebrated on a different date (which it was when we used the Julian calendar), the church would have had a significant feast day to coincide with such a major celebration in the northern hemisphere.

Is that why it’s particularly popular in northern Europe? Bingo, mysterious person. St. John’s Day is celebrated all over the world, but the biggest celebrations occur in traditionally Christian nations well above the equator. In strongly Christian countries like Ecuador, where there is little change in sunrise and sunset throughout the year, it’s not such a big deal. But in Tallinn, Estonia, the sun sets at about 10:45 p.m. on the summer solstice and 3:30 p.m. on the winter solstice. St. John’s Day is just an extension of the reverence these places have for the summer solstice.

But isn’t it celebrated in Brazil? Yes, and other places where colonial powers instilled their traditions. Joao Fernandes, an early Portuguese explorer, was particularly devoted to the holiday and took John the Baptist as the patron saint of his exploits at Pernambuco, which is where St. John’s day is celebrated most in Brazil today. Fernandes had canons fire salutes around the camp all day long in celebration. This was in no small part because he shared the same name with the saint.

John the Baptist is also the patron saint of French Canada. And Turin, Italy and Porto, Portugal and numerous other places as well. That’s why Quebec celebrates June 24 as its national day.

Is it celebrated the same everywhere? Not quite, though most celebrations share one thing in common: fire. If there’s one thing everyone does on St. John’s Eve, it’s get rid of their old furniture and spare kindling in a giant bonfire. Or if you’re in Shetland, Scotland, where wood is in short supply, your excess heather and peat.

The city of Poznan in Poland had a unique take on the fire tradition in 2012, when they released 8,000 Chinese lanterns into the sky on St. John’s Night, setting a world record in the process.

Bonfires are more typical and are found everywhere, from prominent mountain peaks to valleys and plains. If you’re a traditional fisherman from Brittany, France…

I’m not. Well, if you were, you’d even light a fire on top of your ship’s mainmast to celebrate with your fishing fleet. Curiously, Breton fisherman are said to have a fear of tailors, another group that John the Baptist patronizes.

Elsewhere, the celebrations have unique local flavor. In Scandinavia, figures of witches are added to the flames because, as on Halloween, demons and evil spirits are said to be able to roam freely this day. Up until the 1700s, the French would incinerate cats by the sackful and chase a flaming cat through the streets, evil incarnate as they were (the cats, not the French… ostensibly).

Latvians eat a special cheese flavored with caraway seeds. Ukrainians eat eggs, dumplings and liquor for dinner. Ukrainians will also symbolically wash themselves with the morning dew after watching the sun rise, as do the Lithuanians.

The Irish and others will set a wagon wheel on fire and roll it down a hill to symbolize the sun’s decline. With any luck, there’s nothing flammable at the bottom. Many cultures will dress in traditional costumes. Russians douse each other with water in one of the few actual nods to John the Baptist. The Swedes, celebrating their Midsommar festival a few days before St. John’s Day, raise a giant pole that is supposed to imbue the earth with fertile soil.

Sounds phallic. Indeed. In fact, most rites and rituals surrounding the summer solstice have to do with fertility. Many of the cultures celebrating St. John’s incorporate dancing and singing erotic songs into the celebrations, much to the consternation of the Church, I expect. It’s said to be a good time to predict who will be your future spouse, as well.

No need. Well, another common activity is jumping through the flames. It’s said to cleanse and purify the soul. Or you could wear a garland of flowers.

Not really for me, either. Can I just see some photos? Sure. Check out a slideshow of St. John’s Day (and Night) celebrations from around the world below.

Hope you all had a happy Halloween, and came up with some creative travel costumes (my family and I went as Matryoshkas, or Russian nesting dolls). Now that the calendar has flipped over into November, it’s a time to honor our beloved who have passed on All Saints’ Day, or as it is known in Mexico, Dia de los Muertos. Skeletons and skulls are a pretty common theme in Day of the Dead decor and art, as demonstrated by our own Pam Mandel’s Halloween costume, continuing on the scary feel of Halloween. The skulls in today’s Photo of the Day aren’t Mexican, they’re French, from the Paris catacombs, which contain the bones of millions of Parisians. The remains are made extra spooky with the company of a devil, of the stuffed toy Tasmanian sort, though I suspect he was an addition by Australian photographer BaboMike.

If you can’t make it to Mexico this year, Denver has some Day of the Dead events too.

We like being scared year-round, so add your spookiest shots to the Gadling Flickr pool for an upcoming Photo of the Day.

I have a hideous confession to make. I’m absolutely fascinated by medical techniques and beauty rituals practiced in other countries. No matter how archaic, revolting (to our Western sensibilities), or dubious, I can’t get enough of reading about or watching this stuff. That said, there’s no way you’ll find me willingly engaging in these activities, so it’s a vicarious thrill.

Since it’s almost Halloween, I thought this YouTube clip of an American having his ear cleaned by a street vendor in Benares, India, would make for some pretty scary viewing. It’s not the practice I object to; it’s the concept of “no sterilization.” Just remember to pack the Q-tips on your next overseas trip.

For travelers who want to get away from the fake blood and costumed zombies this Halloween, there is more authentic experience to be had at Zambia’s Kasanka National Park. The spectacle is said to be the world’s largest mammal migration, with 8 million straw-colored fruit bats arriving from the Congo to eat the wild musuku fruits in the park.

During the migration an overwhelming amount of bats spiral through the skies, screeching and colliding as they return each year to settle in the fruit trees, covering them until there is no longer visible bark. The most memorable time to watch is at sunset, when the bats fly out to find food, creating a thick straw blanket in the sky.

Said Jim Holden, President of African Travel, Inc., in a press release, “The annual migration of millions of bats from the Democratic Republic of the Congo across the border to Kasanka National Park is an astonishing sight. Africa is full of such natural wonders, and most of them are not well known, as with this natural occurrence.”
